2x8 F4-3600C15-8GTZ Max temp 37c so far, with active cooling.
Error free overnight with memtest64, a few hours of prime and a few times around Hircines Haunt. Using Ryzen DRAM Calculator 18.104.22.168. 3800 fast preset with rec settings and 1.47v:
I just plugged in the numbers and it worked. It was also stable at 1.46v but lost some performance.
I might just stick to bios 2501 and the last chipset driver for a while and give them a couple revisions with the new agesa to get the rest of the kinks out. Or just wait for a zen 3 bios.
Completely removing the system from power and discharging residual power does result in a c5 on a true cold boot, but I have to go out of my way to do that and my profiles are saved and never fail to boot after they're reloaded.
